Making Custom types documentation example work

[bgctw]

I try to redo the Custom Types example of the documentation, but I am not able to read proper Person types.

using Arrow: Arrow, ArrowTypes
struct Person
    id::Int
    name::String
end
ArrowTypes.arrowname(::Type{Person}) = :Person
ArrowTypes.JuliaType(::Val{:Person}) = Person

table = (col1=[Person(1, "Bob"), Person(2, "Jane")],)
io = IOBuffer()
Arrow.write(io, table)
seekstart(io)
table2 = Arrow.Table(io)
p1 = first(table2)
typeof(p1)  # Arrow.Struct{Person, ...}
p1 isa Person # false

Both with Julia 1.8.4 and 1.8.5
In an otherwise empty environment:

(jl_t4jDSi) pkg> st
Status `/tmp/jl_t4jDSi/Project.toml`
  [69666777] Arrow v2.4.2

And also with the current master (dev https://github.com/apache/arrow-julia.git)

(jl_t4jDSi) pkg> st
Status `/tmp/jl_t4jDSi/Project.toml`
  [69666777] Arrow v2.4.2 `~/julia/dev/Arrow`

[evetion]

julia> first(p1)
Person(1, "Bob")

julia> first(p1) isa Person
true

first(table2) gets you the first column, which isn't a Person, but a vector of them.

Oh. Thanks for this explanation.
